Dypsis decaryi runners question

[Almisa]

Here is my (potted) Triangle Palm still recovering from the last Christmas freeze - even with protection she defoliates each year.  Ive had good success in bringing her back thus far - no place for her in the ground.  Anyway -  I am always intrigued by the ‘runners’ this species puts out towards the bottom fronds , each with a sort of ‘pod’ at the end tip of the runner.  Can someone enlighten me as to what these are?

They look like weeds in the potting soil.

Is this planted in the ground or in a pot?

That is called a ....,(???). It' s a protection of the leaflet blades, joining them together when the frond is still a spear.... I see this long filaments also on my D. decipiens.

Sorry for answer delay. These runners a come directly from the tree .  I think Alberto provided the answer!

My Bismarck’s have those on the new fronds. They fall off after a week or 2. Helps hold the spear together.

Also, I think that’s rustweed trying to overtake your palm.

I have those hanging on mine too. I leave them on, I think it adds to the great look of these palms.

Mine, in Vero Beach near the airport, which hit 26º F in the 2010-11 cold spell, cold rain, and freeze, did suffer leaf damage that year.  None since, with temperatures going only a degree or two below freezing.  It's under a bit of high canopy (south Florida slash pine and a growing live oak, Quercus virginiana), which has perhaps contributed to its crown no longer forming a tidy triangle.  The leaves are substantial, about as big and heavy as Archontophoenix tuckeri.

Almisa, those long filaments are called ‘reins’, a connective tissue at the end of the leaflets as the spear emerges. They are brittle and waxy and eventually break off.
